CLIPPER.

Application led June 3, 1926. Serial No. 113,412.

This invention relates to improvements in clippers, particularly adaptedthough not necessarily limited in its use in barber shops, and one ofthe objects of the invention is to provide an improved device of thischaracter wherein the actuating mechanism embodies an electro-magnetwhich controls the vibration of an armature, both the armature andmagnet being located within the handle of the device, the clippers beingoperated by means of the electro-magnet to which alternating current issupplied.

A further object is to provide in a clipper of this character, improvedmeans whereby a vibrator or massage device may be readily connected tothe armature and improved means for controlling the extent of movementof the armature under the influence of the electro-magnet in accordancewith the work to be performed by the device.

A further obj ect is to provide an improved device of this characterwhich will be of a simple and compact construction, effective andefficient in operation, and of a size and shape convenient to be readilyhandled by an operator.

To the attainment of these ends and the accomplishment of other new anduseful objects as will appear, the invention consists 1n the features ofnovelty in substantially the construction, combination and arrangementof the several parts hereinafter more fully described and claimed andshown in the accompanying drawings illustrating this invention andinwhich Figure 1 is a top plan view of a devlce of this characterconstructed in accordance with the principles of this invention.

Figure 10 is a detail perspective view of the armature.

Figure 1'1 is a detail plan view of the spring washer for maintainingthe controlling member for the armature in its adjusted position.

Figure 12 is a detail perspective view of a vibrator attachment.Referring more particularly to the drawings the numeral 15 designates anopen casing of any desired size and configuration, at the forward end ofwhich is secured a stationary cutter member 16, the latter beingpreferably arranged at an angle to the longitudinal axis of the casingand being provided with teeth 17, usual in cutters of this character.Reciprocating upon the cutter member 16 is a cutter 18 which is guidedin its action preferably by means of a member 19 secured thereto andwhich operates in a groove 20 in the upper face of the member 16.

Arranged within the casing 15 is an electromagnet 21, the core 22 ofwhich is provided with a slot 23 through which a screw 24 passes and bymeans of which screw and slot the electromagnet is adapted to beadjusted laterally Within the casing. An armature 25 is provided forreciprocating t-he cutter blade 18. connected with it a spring member 26and the armature is mounted for vibratory movement by means of a screw27 which passes through an opening 28 in the armature and is threadedinto a post 29 within the casing 15.

The screw 27 co-operates with a clamping member 27a that rests upon thebottom of the casing to hold the armature and spring against movementabout the screw 27 as a pivot.

The armature is supported adjacent one end thereof and the otherextremity of the armature is preferably reduced as at 30 and is roundedas at 31 upon its lower face, thereduced portion 30 being arranged at aninclined angle to the armature and projecting over the blade 18 andspaced therefrom.

A leaf spring 32 is secured by one end as at 33 to the blade 18. Theother end of the spring is shaped to form an open seat 34 having slots35 in the walls thereof and tlie bottom of the seat is spaced above theadjacent face of the blade 18 and is rounded to conform to the contourof the rounded lower face 31 of the portion 30 of the armature. Thereduced portion 30 of the armature 25 rests within the seat 31, and apin 36 passes This armature has A through the lend 30 of the armatureand enters the slots in the leaf spring 32. The spring and the pin 36form a resilient connection between the blade 18 and the armature 25.The stress of the armature upon the resilient member 32 serves as ameans for holding the plate 18 against the stationary plate 16 and atthe same time the armature will have a free movement with respect to theblade 18. The curved surfaces 31 of the portion 30 of the armature andthe correspondingly shaped seat in the resilient member 32 will permitthe armature and reciprocating blade to relatively rock and therebyinsure an equal pressure upon both ends of the reciprocating blade. Withthis construction the armature may be short and stili' and adapted tospring only in directions towards and away from the magnet, and thespring 32 will provide all the necessary spring or tension 0n the blade18.

'The stress of the spring 32 may be varied by raising and lowering theend 30 of the armature. This is accomplished by swinging the armatureabout the pivot formed by the screw 27 after the screw has beenloosened.

Any suitable means may be provided for thus adjusting the armature but asimple and eiiieient means vembodies a threaded socket 37 projectingfrom the other end of the armature. This 'socket is disposed betweenspaced lugs or posts 38 in the casing 15 and a screw 39 is threaded intothe socket. The screw is provided with an open circumferential groove 40in the body portion thereof, and stationary pins or lugs 41 carried bythe posts 38 extend into the groove 40 of the screw 39 so that the screwwill be held against longitudinal movement but when the screw is rotatedin any suitable manner, the socket 37 will be moved longitudinally ofthe screw,

with the result that the armature 25 will be rocked or moved about itspivot.

lVhen the socket end of the armature is elevated the extremity 30 willbe depressed and this will increase the tension upon the spring 32,likewise when the socket end 0f the armature is depressed the extremity30 of the armature will be raised and the tension of the spring 32 willbe decreased.

The eleetromagnet 21 receives its supply of electric current throughsuitable conductors 42, and these conductors are arranged within thecasing 15 and are threaded through an opening 43 in the post 38, acontrolling switch 44 being provided within the casing for controllingthe current to the magnet.

It will be thus noted that with this improved construction when theelectromagnet is energized the armature 25 will be attracted and theextent of this movement of the armature will be controlled by theengagement of a portion 45 of the armature with a portion 46 tractedagainst the stress of the-spring 26. When the electromagnet isdeenergized the armature will return to its normal position.

This vibration of the armature 25 will impart a reciprocating movementto the blade 18.

A cover .47 is provided for the casing and this cover'is .provided witha projection 48 at the forward end thereof and one or more projections49 on the edge of its body p0rtion, and which projections serve as ameans for properly positioning the cover upon the casing, theprojections 49 being adapted to enter a suitable recess 50 in the Wallof the casing.

A separate vibrator or implement 51 is provided lfor use in connectionwith this device, whereby the device may be employed for operationsother than clipping operations, and this attachment is adapted to beapplied without disconnecting any of the parts of the cutter or clippermechanism.

To that end the attachment 51 is provided with a stem 52 having athreaded extremity 53 adapted' to be threaded into a socket 54 carriedby the armature 25, and which socket opens laterally of the armature,the casing 15 being provided with an opening 55 in alinement with thesocket 54.

The attachment 51 is adapted to be connected by passing the stem 52through the opening 55 and threading the extremity of the stem into thesocket 54.

In use, a long stroke should be given to the armature when using thevibrator attachment, whereas when the implement is used aS a clipper itis desirable to impart a shorter stroke to the armature. The vibrationof the armature is adapted to be controlled by means of a screw device56 which is threaded through the cover 47 and is preferably providedwith a fibre element 57 secured to' the end thereof. The extremity ofthe screw 56 is adapted to engage a surface 58 carried by the armature25 and formed in any suitable manner, the surface 58 being providedadjacent the free end of the armature.

When the vibrator is employed the extent of operation of the cutterblade will serve as an indicator to indica-te the force of operation ofthe vibrator.

l/Vhen the device is used as a. hair clipper, the vibration of thearmature may be reduced so that the blade 18 will travel 'the properdistance and this is accomplished by applying a light downward pressureupon the free end of the armature by forcing the end of the screw 56againstthe surface 58, this will result in an increased frictionalpressure between the end of the screw 56 and the surface 58 on thearmature.

When it is desired to produce a longer stroke to the armature thispressure of the screw 56 upon the surface 58 is relieved.

It will therefore be manifest that both implements, although they havedifferent functions and operations, are controlled in their operation bythe adjustment of the screw 56 to regulate or control the extent ofvibratory movement of the armature.

As a means for holding the screw in its adjusted position a springwasher 59 is provided which is secured adjacent the lower face of thecover member 47 and is held against rotation-'by means of an anchoringpin 60.

The washer 59 being of a spring construction, will grip the threaded'shank of the screw 56 andv will frictionally bind or retain the Screw inits adjusted position and thereby prevent the same from Working looseunder the vibration of the armature.

The fibre element 57 engaging the surface 58 operates to reducefriction.

As a means for providing an extended portion into which the screw` 61,which secures one end of the pole iece 22, passes (see Figure 8) thebottom o the casing 15 is provided with an upstanding threaded lug 62which enters a recess 63 in the pole piece 22.

With this improved construction it will be manifest that the device isadapted to be converted from a clipper into a vibrator or massage devicewithout interfering with or dismantling any of the parts of the clipper.

This is accomplished by simply attaching the element 51 to the armature.

When desired to use as a clipper, the element 51 may be readily removed.
